ITEM 3.
QUANTITATIVE AND QUALITATIVE DISCLOSURES
ABOUT MARKET
RISK
Market risk is the exposure to loss resulting from changes in market factors such as interest rates, foreign currency
exchange rates, commodity prices and equity prices. The primary market risks that we are exposed to are interest rate risk,
prepayment risk, spread risk, liquidity risk, extension risk and counterparty credit risk.
Interest Rate Risk
Interest rate risk is highly sensitive to many factors, including governmental monetary and tax policies, domestic and
international economic and political considerations and other factors beyond our control.
Changes in the general level of interest rates can affect our net interest income, which is the difference between the
interest income earned on interest-earning assets and the interest expense incurred in connection with our interest-bearing
liabilities, by affecting the spread between our interest-earning assets and interest-bearing liabilities. Changes in the level of
interest rates can also affect the rate of prepayments of our securities and the value of the RMBS that constitute our
investment portfolio, which affects our net income, ability to realize gains from the sale of these assets and ability to borrow,
and the amount that we can borrow against these securities.
We may utilize a variety of financial instruments in order to limit the effects of changes in interest rates on our
operations. The principal instruments that we use are futures contracts, interest rate swaps and swaptions. These
instruments are intended to serve as an economic hedge against future interest rate increases on our repurchase
agreement borrowings.
Hedging techniques are partly based on assumed levels of prepayments of our Agency RMBS.
If
prepayments are slower or faster than assumed, the life of the Agency RMBS will be longer or shorter, which would reduce
the effectiveness of any hedging strategies we may use and may cause losses on such transactions.
Hedging strategies
involving the use of derivative securities are highly complex and may produce volatile returns.
Hedging techniques are also
limited by the rules relating to REIT qualification.
In order to preserve our REIT status, we may be forced to terminate a
hedging transaction at a time when the transaction is most needed.
Our profitability and the value of our investment portfolio (including derivatives used for hedging purposes) may be
adversely affected during any period as a result of changing interest rates, including changes in the forward yield curve.
Our portfolio of PT RMBS is typically comprised of adjustable-rate RMBS (“ARMs”),
fixed-rate RMBS and hybrid
adjustable-rate RMBS. We generally seek to acquire low duration assets that offer high levels of protection from mortgage
prepayments provided that they are reasonably priced by the market.
Although the duration of an individual asset can
change as a result of changes in interest rates, we strive to maintain a hedged PT RMBS portfolio with an effective duration
of less than 2.0. The stated contractual final maturity of the mortgage loans underlying our portfolio of PT RMBS generally
ranges up to 30 years. However, the effect of prepayments of the underlying mortgage loans tends to shorten the resulting
cash flows from our investments substantially. Prepayments occur for various reasons, including refinancing of underlying
mortgages and loan payoffs in connection with home sales,
and borrowers paying more than their scheduled loan
payments, which accelerates the amortization of the loans.
The duration of our IO and IIO portfolios will vary greatly depending on the structural features of the securities.
While
prepayment activity will always affect the cash flows associated with the securities, the interest only nature of IOs may
cause their durations to become extremely negative when prepayments are high, and less negative when prepayments are
low.
Prepayments affect the durations of IIOs similarly, but the floating rate nature of the coupon of IIOs (which is inversely
related to the level of one month LIBOR) causes their price movements, and model duration, to be affected by changes in
both prepayments and one month LIBOR, both current and anticipated levels.
As a result, the duration of IIO securities will
also vary greatly.
Prepayments on the loans underlying our RMBS can alter the timing of the cash flows from the underlying loans to us.
47
As a result, we gauge the interest rate sensitivity of our assets by measuring their effective duration. While modified duration
measures the price sensitivity of a bond to movements in interest rates, effective duration captures both the movement in
interest rates and the fact that cash flows to a mortgage related security are altered when interest rates move. Accordingly,
when the contract interest rate on a mortgage loan is substantially above prevailing interest rates in the market, the effective
duration of securities collateralized by such loans can be quite low because of expected prepayments.
We face the risk that the market value of our PT RMBS assets will increase or decrease at different rates than that of
our structured RMBS or liabilities, including our hedging instruments. Accordingly, we assess our interest rate risk by
estimating the duration of our assets and the duration of our liabilities. We generally calculate duration using various third
party models.
However, empirical results and various third party models may produce different duration numbers for the
same securities.
The following sensitivity analysis shows the estimated impact on the fair value of our interest rate-sensitive investments
and hedge positions as of September 30, 2021 and December 31, 2020, assuming rates instantaneously fall 200 bps, fall
100 bps, fall 50 bps, rise 50 bps, rise 100 bps and rise 200 bps, adjusted to reflect the impact of convexity, which is the
measure of the sensitivity of our hedge positions and Agency RMBS’ effective duration to movements in interest rates.
All changes in value in the table below are measured as percentage changes from the investment portfolio value and
net asset value at the base interest rate scenario. The base interest rate scenario assumes interest rates and prepayment
projections as of September 30, 2021 and December 31, 2020.
Actual results could differ materially from estimates, especially in the current market environment. To
the extent that
these estimates or other assumptions do not hold true, which is likely in a period of high price volatility, actual results will
likely differ materially from projections and could be larger or smaller than the estimates in the table below. Moreover,
if
different models were employed in the analysis, materially different projections could result. Lastly,
while the table below
reflects the estimated impact of interest rate increases and decreases on a static portfolio, we may from time to time sell any
of our agency securities as a part of the overall management of our investment portfolio.

Interest rate sensitivity is derived from models that are dependent on
inputs and assumptions provided by third parties as well as by our
Manager, and assumes there are no changes
in mortgage spreads and assumes a static portfolio. Actual results could differ

In addition to changes in interest rates, other factors impact the fair value of our interest rate-sensitive investments,
such as the shape of the yield curve, market expectations as to future interest rate changes and other market conditions.
Accordingly, in the event of changes in actual interest rates, the change in the fair value of our assets would likely differ from
that shown above and such difference might be material and adverse to our stockholders.
Prepayment Risk
Because residential borrowers have the option to prepay their mortgage loans at par at any time, we face the risk that
we will experience a return of principal on our investments faster than anticipated. Various factors affect the rate at which
mortgage prepayments occur, including changes in the level of and directional trends in housing prices, interest rates,
general economic conditions, loan age and size, loan-to-value ratio, the location of the property and social and demographic
conditions. Additionally, changes to government sponsored entity underwriting practices or other governmental programs
could also significantly impact prepayment rates or expectations. Generally, prepayments on Agency RMBS increase during
periods of falling mortgage interest rates and decrease during periods of rising mortgage interest rates. However, this may
not always be the case.
We may reinvest principal repayments at a yield that is lower or higher than the yield on the repaid
investment, thus affecting our net interest income by altering the average yield on our assets.
Spread Risk
When the market spread widens between the yield on our Agency RMBS and benchmark interest rates, our net book
value could decline if the value of our Agency RMBS falls by more than the offsetting fair value increases on our hedging
instruments tied to the underlying benchmark interest rates. We refer to this as "spread risk" or "basis risk." The spread risk
associated with our mortgage assets and the resulting fluctuations in fair value of these securities can occur independent of
changes in benchmark interest rates and may relate to other factors impacting the mortgage and fixed income markets,
such as actual or anticipated monetary policy actions by the Fed, market liquidity, or changes in required rates of return on
different assets. Consequently, while we use futures contracts and interest rate swaps and swaptions to attempt to protect
against moves in interest rates, such instruments typically will not protect our net book value against spread risk.
Liquidity Risk
The primary liquidity risk for us arises from financing long-term assets with shorter-term borrowings through repurchase
agreements. Our assets that are pledged to secure repurchase agreements are Agency RMBS and cash. As of September
30, 2021, we had unrestricted cash and cash equivalents of $424.1 million and unpledged securities of approximately $5.4
million (not including unsettled securities purchases or securities pledged to us) available to meet margin calls on our
repurchase agreements and derivative contracts, and for other corporate purposes. However, should the value of our
Agency RMBS pledged as collateral or the value of our derivative instruments suddenly decrease, margin calls relating to
our repurchase and derivative agreements could increase, causing an adverse change in our liquidity position. Further,
there is no assurance that we will always be able to renew (or roll) our repurchase agreements. In addition, our
counterparties have the option to increase our haircuts (margin requirements) on the assets we pledge against repurchase
agreements, thereby reducing the amount that can be borrowed against an asset even if they agree to renew or roll the
repurchase agreement. Significantly higher haircuts can reduce our ability to leverage our portfolio or even force us to sell
assets, especially if correlated with asset price declines or faster prepayment rates on our assets.
Extension Risk
The projected weighted average life and the duration (or interest rate sensitivity) of our investments is based on our
Manager's assumptions regarding the rate at which the borrowers will prepay the underlying mortgage loans. In general, we
use futures contracts and interest rate swaps and swaptions to help manage our funding cost on our investments in the
event that interest rates rise. These hedging instruments allow us to reduce our funding exposure on the notional amount of
the instrument for a specified period of time.
49
However, if prepayment rates decrease in a rising interest rate environment, the average life or duration of our fixed-
rate assets or the fixed-rate portion of the ARMs or other assets generally extends. This could have a negative impact on
our results from operations, as our hedging instrument expirations are fixed and will, therefore, cover a smaller percentage
of our funding exposure on our mortgage assets to the extent that their average lives increase due to slower prepayments.
This situation may also cause the market value of our Agency RMBS and CMOs collateralized by fixed rate mortgages or
hybrid ARMs to decline by more than otherwise would be the case while most of our hedging instruments would not receive
any incremental offsetting gains. In extreme situations, we may be forced to sell assets to maintain adequate liquidity, which
could cause us to incur realized losses.
Counterparty Credit Risk
We are exposed to counterparty credit risk relating to potential losses that could be recognized in the event that the
counterparties to our repurchase agreements and derivative contracts fail to perform their obligations under such
agreements. The amount of assets we pledge as collateral in accordance with our agreements varies over time based on
the market value and notional amount of such assets as well as the value of our derivative contracts. In the event of a
default by a counterparty, we may not receive payments provided for under the terms of our agreements and may have
difficulty obtaining our assets pledged as collateral under such agreements. Our credit risk related to certain derivative
transactions is largely mitigated through daily adjustments to collateral pledged based on changes in market value and we
limit our counterparties to registered central clearing exchanges and major financial institutions with acceptable credit
ratings, monitoring positions with individual counterparties and adjusting collateral posted as required. However, there is no
guarantee our efforts to manage counterparty credit risk will be successful and we could suffer significant losses if
unsuccessful.
